摘要
采用熔融挤出法制备了高密度聚乙烯(HDPE)与马来酸酐(MAH)的接枝物(HDPE-g-MAH),并用红外光谱证实了接枝反应。以此接枝物为相容剂制备HDPE/PA6共混材料。研究了PA6和相容剂用量对共混材料形态结构、力学性能及阻气性能的影响。SEM表明相容剂可以明显改善HDPE与PA6的相容性。PA6的加入显著提高了HDPE对氧气的阻隔性能。
Maleic anhydride grafted high density polyethylene（HDPE-g-MAH）was prepared by melt extrusion.The infrared spectroscopy confirmed the grafting reaction. HDPE/PA6 blends were prepared with the graft as compatibilizer. Effects of PA6 and compatibilizer content on morphology, mechanical properties and gas barrier properties of the blends were studied. SEM indicated that the compatibilizer （HDPE-g-MAH） could significantly improve the compatibility of HDPE and MAH. The oxygen barrier property of HDPE was significantly enhanced by PA6.
